Technical Note—A Production-Scheduling Problem with Batch Processing

Scheduling Accumulated Rework in a Normal Cycle: Optimal Batch Production with Minimum Rework Cycles

In this paper we consider a single machine system that produces items part of which are defective. The defective items produced in a time period, consisting of several equal cycles, are accumulated and are all reworked in the last cycle of this period called the rework cycle. At the end of the rework cycle the whole process will start all over again. The first significant objective of this stud...

The Batch Loading and Scheduling Problem

This paper discusses a problem that commonly occurs in the batching and schedulingof certainkinds of batch processors. Examplesof these processors include heat treatment facilities, particularly in the steeland ceramicindustries as well as a varietyof operations in the manufacture of integratedcircuits. There are a set of jobs waiting to be processed. The processing time for a batchdependsonly ...

A bi-objective model for a scheduling problem of unrelated parallel batch processing machines with fuzzy parameters by two fuzzy multi-objective meta-heuristics

This paper considers a bi-objective model for a scheduling problem of unrelated parallel batch processing machines to minimize the makespan and maximum tardiness, simultaneously. Each job has a specific size and the data corresponding to its ready time, due date and processing time-dependent machine are uncertain and determined by trapezoidal fuzzy numbers. Each machine has a specific capacity,...

Scheduling in an Assembly-Type Production Chain with Batch Transfer

This paper addresses a three-machine assembly-type flowshop scheduling problem, which frequently arises from manufacturing process management as well as from supply chain management. Machines one and two are arranged in parallel for producing component parts individually, and machine three is an assembly line arranged as the second-stage of a flowshop for processing the component parts in batch...
